News Telegraph: Scientists are still speculating about the meaning of a Roman army brooch discovered in Unst on Shetland. Roman artifacts are rarely found as far north as the Shetland Islands, and this is why archaeologists are very excited about the recent discovery of a Roman army brooch. Dating from between 50 BCE and 50 CE, the fibula, which was used as a clothing clasp, was discovered on Unst. Experts are now speculating on whether the artifact came from a Roman recruit returning home or was a trade piece. "It could have been used as something to barter with and is a very special find," said Dr Alan Leslie of Glasgow University.
